All states: EVV requirements map
In short: Open model on the state system (AuthentiCare), with outside EVV systems allowed. Claims are not yet denied for missing EVV. Change ahead: New Hampshire plans to start denying claims that skip EVV and has promised at least 30 days notice. No date is set.
| EVV model | Open. Agencies can use the state system or their own EVV software. |
|---|---|
| State EVV system | AuthentiCare (Fiserv), offered to providers at no cost. |
| Aggregator | AuthentiCare aggregator (Fiserv) |
| Can I use my own EVV vendor? | Yes. File the state declaration and third-party attestation forms, and your vendor sets up with AuthentiCare. |
| Are claims denied without EVV? | Not yet. As of September 17, 2026 the state had not turned on hard denials. |
| Managed care | The state has said a future denial edit would apply to fee-for-service and managed care claims together. |
| EVV start date | June 1, 2024 |

New Hampshire uses an open EVV model, which the Department of Health and Human Services (DHHS) calls an Open Vendor EVV Design Model. The state offers AuthentiCare, a Fiserv system, to providers at no cost. Agencies can use AuthentiCare or keep their own EVV software, as long as that software sends visit data to the AuthentiCare aggregator. EVV has been live statewide since June 1, 2024.
Every provider files the NH EVV System Declaration Form to tell the state which system it uses. Agencies that use their own software also file the Third-Party Attestation Form, and their vendor then contacts AuthentiCare support to set up a connection. The state describes onboarding and testing as a one-time step for each vendor. All visits, whether they are captured in AuthentiCare or in another system, have to reach AuthentiCare for state reporting.
New Hampshire does not publish a list of approved third-party EVV vendors, so ask any vendor you are considering whether it is already set up to send data to the New Hampshire aggregator. More detail is on the DHHS EVV page.
EVV applies to the services on the state's List of Medicaid Services that Require EVV, and only when the service is delivered in the member's home. The current list, revised in May 2026, covers Choices for Independence (CFI) waiver services and Medicaid State Plan services. DHHS says code and modifier combinations that are not on the list may be billed directly without EVV.
Time-of-day modifiers are part of the list for personal care, home health aide and private duty nursing codes, so the visit record needs to carry the right one. Check your exact codes and modifiers against the state services list.
The May 2026 list has no rows for the Developmental Disabilities, Acquired Brain Disorder or In Home Supports waivers. Those waivers were named when the program was designed, but their services are not on the current list. A member on one of those waivers who receives a State Plan service on the list is covered through that State Plan code.
A few other rules matter day to day:
Not yet. As of the state's September 17, 2026 provider meeting, New Hampshire had not started hard denials for claims that skip EVV. Services on the EVV list are meant to be confirmed and billed through AuthentiCare, but the state is still in a soft edit phase. That is true for fee-for-service and for managed care claims.
This is different from what the state first planned. The May 2024 go-live notice and the July 2024 FAQ said denials would begin about 60 days after go-live. That did not happen, so older state documents that describe denials are out of date. The July 2026 provider meeting minutes describe the EVV message on a managed care claim as informational, not a denial.
The lack of a hard denial does not make EVV optional. The requirement has been in place since June 1, 2024. Inside AuthentiCare, a visit with a critical exception cannot be confirmed for billing until the exception is fixed. Agencies that clear exceptions every day now will have much less to change when the state turns denials on.
Important: DHHS plans a hard edit that would deny claims for EVV-listed services that are not sent through an EVV system. No start date has been set. The state has said it will give providers at least 30 days notice first, and that the edit would apply to fee-for-service and managed care claims at the same time. Watch the DHHS provider meeting minutes for the notice.
Other items the state has discussed, none of which we would treat as final until DHHS confirms them:
We did not find a date for adding Developmental Disabilities, Acquired Brain Disorder or In Home Supports waiver services to the EVV list. If you provide those services, ask DHHS before you assume either answer.
